ANTIGLARE SUPPORTS AND CONTRAST AMPLIFYING SUPPORTS FOR REFLECTED POLARIZED LIGHT

A support designed for observing between intersecting polarizers an object located in its vicinity in a medium (3) of index n0 with incident convergent incoherent illumination under an angle theta0 at a wavelength lambda. The support includes a substrate (1) with complex refractive index n2 and a la...

More Information
Summary:A support designed for observing between intersecting polarizers an object located in its vicinity in a medium (3) of index n0 with incident convergent incoherent illumination under an angle theta0 at a wavelength lambda. The support includes a substrate (1) with complex refractive index n2 and a layer (2) of refractive index n1 and thickness e1. The value of the thickness e1 of the layer (2) is at ±2% such that d2√/de21 lnIóI2=0 with Ó=Ó01+Ó12 (1+pi01)e(-2jbeta1)+Ó01 pi12e (-4jbeta1)/1+r01(p)+r12(p)e(-2jbeta1))(1+r01(s)r12(s)e(-2jbeta1)). Observation devices incorporating such a support are also disclosed.
